There are two stages to the construction process; ‘as design’ and ‘as built’, and an SBEM calculation is required for both stages. ‘As design’ refers to the initial design process. This SBEM calculation will be carried out prior to construction work beginning.
Once the work has been completed, another SBEM calculation is required. This is known as the ‘As built’ stage.
The SBEM calculation carried out during the ‘as design’ stage should be detailed and comprehensive so that it is reflective of the final, ‘as built’ SBEM calculation. This ensures that Building Control can sign it off in a smooth and efficient manner.
We recommend that you get your SBEM completed as early as possible. We would suggest that you involve your assessor as part of the Design team in order to identify any shortfalls before they become a problem.
